Malpractice, tort reform, and you: an introduction to risk management

The current malpractice crisis has been called the "perfect storm". Doctors are finding practice costs unsustainable. Patients are finding access to care jeopardized. Cost of care is escalating. The system does not deter medical error, compensate most injured victims, produce any result quickly. These factors are creating enough of a crisis to urgently address and merit prompt solution. However, if history is any guide, the debate over malpractice will continue to rage. Reforms will likely be slow. Thus the practicing gastroenterologist, while working for or supporting efforts toward a solution, is well advised to keep up to date with the practice of gastroenterology, but also understand the medical legal matters and have a risk management strategy that will hopefully help keep the malpractice crisis a theoretical rather than personal concern. The following articles in this series are intended to help.     

Methods to prevent colonic injury in pelvic radiation

PURPOSE: Radiation has become an adjunct in the treatment of pelvic malignancies. Attempts to prevent adjacent tissue injury have met with varying degrees of success, and the purpose of this study was to investigate potential radioprotective effects of an elemental diet, sodium meclofenamate, and vitamin A in an animal model of acute and chronic pelvic radiation previously described. METHODS: Female Sprague-Dawley rats, 200–250 grams, were anesthetized and then received 900 rads of pelvic radiation once per week for five weeks for a total of 4500 rads. Animals were divided into five groups. Treatment groups received radiation and elemental diet, radiation and vitamin A, radiation and sodium meclofenamate. Control animals received anesthesia only and no radiation. Vitamin A was given as a supplement to (662 IU/kg) standard rat chow. Elemental diet was given as a commercially available formula, whereas sodium meclofenamate was given as a postoperative supplement (5 mg/kg/day). All animals were given these treatments during the course of radiation therapy only. Histology of distal colon was measured at one week, five weeks, six months, and one year postradiation therapy. The distal two cm of colon were removed at necropsy and fixed in 10 percent formalin at each of the above time points. Histologic grade was determined by a previously described grading scale. RESULTS: Results showed a qualitative radiation injury that could be documented at one and five weeks postradiation. Elemental diet, vitamin A, and sodium meclofenamate prevented histologic changes that occurred at these time points. No difference in histologic grade was seen between any groups at six months and one year postradiation therapy. CONCLUSION: In summary, our model of pelvic radiation produces a definable radiation injury within the colon at one and five weeks postradiation. Use of elemental diet, vitamin A, and sodium meclofenamate prevented these changes.     

Systematic review of medical therapy to prevent recurrent diverticulitis

Aim and background

One of today’s controversies remains the prevention of recurrent diverticulitis. Current guidelines advise a conservative approach, based on studies showing low recurrence rates and a high operative morbidity and mortality. Conservative measures in prevention recurrence are dietary advises and medical therapies, including probiotics and 5-aminosalicylic acid.

Objectives

The aim of this systematic review is to assess whether medical or dietary therapies can prevent recurrent diverticulitis after a primary episode of acute diverticulitis.

Method and search strategy

We searched different databases for papers published between January 1966 and January 2011.

Study selection

Clinical studies were eligible for inclusion if they assessed the prevention of recurrent diverticulitis with a medical or dietary therapy. Exclusion criteria were studies without a control group.

Results

Three randomized controlled trials (RCT), all with a Jadad quality score of 2 out of 5, were included in this systematic review. Mesalazine results in significantly less disease recurrence and fewer symptoms after an acute episode. The use of probiotics decreases symptoms but does not reduce recurrence. No difference in effect is seen when Balsalazide is added to probiotics compared to probiotics only. No relevant studies on dietary therapy/advices or antibiotics for prevention of recurrent diverticulitis were found.

Conclusion

The evidence that supports medical therapy to prevent recurrent diverticulitis is of poor quality. Treatment with 5-aminosalicylic acid seems promising. Based on current data, no recommendation of any non-operative relapse prevention therapy for diverticular disease can be made.     

Risk of HCV transmission after needlestick injury, and the efficacy of short-duration interferon administration to prevent HCV transmission to medical personnel

Background. We carried out this study to assess the risk of hepatitis C virus (HCV) transmission after needlestick injuries in medical personnel, and to evaluate the efficacy of short-duration interferon administration to prevent HCV transmission. Methods. A total of 684 personnel who had been occupationally exposed to an anti-HCV-positive source and followed for more than 3 months were retrospectively examined. Results. Of the 684 subjects, 279 (41%) were treated with 1 to 3 days of interferon either just after or 1 to 12 days after the injury. One case of HCV infection was found in each of the treated (1/279; 0.4%) and nontreated (1/405; 0.2%) groups. There was no significant difference in the transmission of HCV between the two groups. Both infected patients were treated with interferon after developing acute hepatitis, and HCV was subsequently cleared. Conclusions. There is a lower risk of HCV transmission after needlestick accident than previously reported, and short-duration interferon administration at an early stage after the needlestick injury, to prevent HCV transmission, is unnecessary.     

Asymptomatic individuals at genetic risk of haemochromatosis take appropriate steps to prevent disease related to iron overload

Background/Aims: If community screening for hereditary haemochromatosis is to be considered, compliance with preventative measures and absence of significant psychological morbidity must be demonstrated. Methods: Workplace screening for the HFE C282Y mutation and then clinical care for C282Y homozygotes was instituted. Data were collected on understanding of test results, perceived health status and anxiety for C282Y homozygotes compared with controls. Uptake of clinical care, compliance and response to treatment and changes in diet were monitored for up to 4 years for C282Y homozygotes. Results: After 11 307 individuals were screened, 40/47 (85%) newly identified C282Y homozygotes completed questionnaires 12 months after diagnosis compared with 79/126 (63%) of controls. Significantly more C282Y homozygotes correctly remembered their test result compared with controls (95 vs 51%, P<0.0001). No significant difference in perceived health status was observed within or between the two groups at 12 months compared with baseline. Anxiety levels decreased significantly for C282Y homozygotes at 12 months compared with before testing (P<0.05). Forty‐five of the 47 (95.8%) C282Y homozygotes accessed clinical care for at least 12 months. All 22 participants requiring therapeutic venesection complied with treatment for at least 12 months (range 12–47 months). Conclusion: Individuals at a high genetic risk of developing haemochromatosis use clinical services appropriately, maintain their health and are not ‘worried well’. Population genetic screening for haemochromatosis can be conducted in the work place in a way that is acceptable and beneficial to participants.

Cost-effectiveness of interventions to prevent alcohol-related disease and injury in Australia

Aims   To evaluate cost-effectiveness of eight interventions for reducing alcohol-attributable harm and determine the optimal intervention mix.
Methods   Interventions include volumetric taxation, advertising bans, an increase in minimum legal drinking age, licensing controls on operating hours, brief intervention (with and without general practitioner telemarketing and support), drink driving campaigns, random breath testing and residential treatment for alcohol dependence (with and without naltrexone). Cost-effectiveness is modelled over the life-time of the Australian population in 2003, with all costs and health outcomes evaluated from an Australian health sector perspective. Each intervention is compared with current practice, and the most cost-effective options are then combined to determine the optimal intervention mix.
Measurements   Cost-effectiveness is measured in 2003 Australian dollars per disability adjusted life year averted.
Findings   Although current alcohol intervention in Australia (random breath testing) is cost-effective, if the current spending of $71 million could be invested in a more cost-effective combination of interventions, more than 10 times the amount of health gain could be achieved. Taken as a package of interventions, all seven preventive interventions would be a cost-effective investment that could lead to substantial improvement in population health; only residential treatment is not cost-effective.
Conclusions   Based on current evidence, interventions to reduce harm from alcohol are highly recommended. The potential reduction in costs of treating alcohol-related diseases and injuries mean that substantial improvements in population health can be achieved at a relatively low cost to the health sector.
